PA: 11.mixed equation practice

Front

1x is the same as x.

Back

True. This is because multiplying a variable by 1 does not change its value.

Front

Solve: -9x + 15 = -30. Type the numerical value only!

Back

5

Front

Rewrite using the distributive property: -(x - 5)

Back

-x + 5

Front

Solve for x: -5x = 25

Back

x = -5

Front

Solve: x + x + x + x + x - 13 - x = 7. Type in the numerical answer only!

Back

5

Front

What is the distributive property?

Back

The distributive property states that a(b + c) = ab + ac, allowing you to multiply a single term by two or more terms inside a set of parentheses.

Front

What does it mean to solve for x?

Back

To solve for x means to find the value of the variable x that makes the equation true.

Front

What is a mixed equation?

Back

A mixed equation is an equation that includes both constants and variables, often requiring different operations to solve.

Front

What is the first step in solving the equation -3x + 12 = 0?

Back

The first step is to isolate the variable term by subtracting 12 from both sides.

Front

If 2x = 10, what is x?

Back

x = 5, because you divide both sides by 2.
